What is new? is the cooperation between Michelin and General Motors to finally bring these tires in production!  The new revolutionary tires are called “Uptis” which is an acronym – Unique Puncture-proof Tyre System.

From then on, and given that everything is going well, there is a forecast to go into production around 2024.
